RICHARD SCHRGDLEIN, OF AUSOHA, AUSTRIA-HUNGARY.

CAR STARTER AND BRAKE.

SPECIFICATION forming part of Letters Patent No.'501,447, dated July 11,1893.

Application filed October 8, 1892. Serial No. 448,287. (No model.)

To aZZ whom it may concern:

Be it known that I, RICHARD SOHRoDLEIN, of Auscha, near Leitmeritz,Bohemia, Austria-Hungary, have invented certain new and usefulImprovements in Apparatusfor Braking and Starting Vehicles, of which thefollowing is a full, clear, and exact specification.

This invention relates to apparatus for braking and starting railwaycars and other vehicles, and has for its object to provide novel meanswhereby the momentum of the vehicle, when the brakes are applied, storespower heretofore wasted, which power is utilized for restarting, orassisting in restarting the vehicle at the proper time.

To accomplish this object my invention involves the features ofconstruction and the combination or arrangement of parts hereinafterdescribed and claimed, reference being made to the accompanyingdrawings, in which- Figures I and I, when taken together, represent asectional plan view of my invention in connection with two car axles ofa car. Figs. II and II, when taken together, represent a plan view ofthe same. Fig. III is a cross sectional view taken on the line A A ofFig. I. Fig. IV is a cross sectional view taken on the line B B of Fig.I; and Fig. V is a longitudinal sectional view of the air reser- V011.In order to enable thoseskilled in the art to make and use my invention,I will now describe the same in detail, referring to the drawingswherein- The letters a a indicate the axles of a railway car or othervehicle, provided respectivelywith friction gear wheels I) b, and e 6counter shafts arranged in juxtaposition tothe car axles. Thecounter-shaft e is provided with a friction-driven gear-wheel d, andwith cranks f connected respectively with the piston-rods of pistons Kmoving respectively in cylinders q. The counter shaft 6 is also providedwith a suitable frame comprisin g links 0 which support the journal oraxle of a transmitting friction gear-wheel c adapted to be moved intoand out of contact with the friction gear-wheel b on the axle a. Theframe composed of the link c is pivotally suspended by a frame composedof links a suitably suspended from a horizontal rod .0

in such manner that when the said rod is moved in the direction of thearrow I, Fig. II, the transmitting gear 0 is thrown into engagement withthe friction gear-wheel b, and the rotary motion of the car axle a. istransmitted to the gear-wheel d for rotating the counter-shaft e, andthus causing the cranks f to reciprocate the pistons K. An air reservoirn, interposed between the cylinders g, is provided with suitable pipeconnections n leading respectively to the cylinders g, and the latterare provided with air valves Z, while the pistons K are provided withair valves 2', all in such manner that when the pistons arereciprocated, as before explained, atmospheric air is pumped into andcompressed in the air reservoir n, thereby storing energy to beutilized, as will hereinafter appear.

The counter-shaft e is provided with cranks f connected respectivelywith the piston g ods of pistons K, having oblique passages afriction-driven gear wheel d, and with a frame composed of links 0 whichsupport the journal or axle of a friction-transmitting gearwheel 0adapted to be moved into and out of engagement with the frictiongear-wheel b on the car axle a. The frame composed of the links a issupported by a frame composed of links 0 pivotally suspended from Thecounter-shaft e is also provided with the horizontal rod 0, all in suchmanner that when said rod is moved in the direction of the arrow II,Fig. II, the friction-transmitting gear-wheel c is moved into engagementwith the friction-gear wheel I). The pistons K are each formed with anoblique passage Z, which, in the position shown. in Fig. I communicatewith the air inlet 7' of pipes or passages q that connect the cylindersg with the air reservoir n. The cylinders g are provided with channels SS and when the parts are in the position, Fig. I and a valve 10 whichgoverns communication with the air reservoir 01. is opened, ashereinafter explained, the compressed air will flow through the pipes orpassages q, inlets a", passages Z, and channels S to the spaces 15behind the pistons K, thereby forcing the pistons toward the oppositeends of the cylinders. When the pistons in their forward stroke comeinto such position that the oblique passages Z communicate with thechannels S of the ports the compressed air will flow intothe spacet inordertoimpart back stroke to the pistons. The exhausted compressed airpasses from the cylinders through the ports to it, which latter open tothe external atmosphere.

A check-valve m is provided on the air-reservoir n to permit the air toflow from the pipes or channels 02. into the air reservoir, Whilepreventing escape of the air from the reservoir back through said pipesor channels n.

The horizontal rod 0 is located below the frame of the car or vehicleand the rods of several cars or vehicles constituting a train may becoupled together for simultaneous movement. The rod 0 is provided with awedge or projection O to engage the valve p, so that when the rod 0 ismoved in the direction of the arrow II, Fig. 2, the wedge or projection0 will open the valve and permit compressed air from the air reservoir nto flow through the pipes or channels q to the cylinders q, as beforeexplained.

In the practical operation of the apparatus, when the brakes of the caror vehicle are applied, the rod 0 is moved in the direction of the arrow1, Fig. II, thereby throwing the friction-transmitting gear-wheel 0 intogear with the friction gear-wheel b, and operating the pistons K toforce air into the air reservoir n, where such air is stored up to besubsequently utilized in restarting the vehicle. In restarting, thesteam-valve of the locomotive is opened so that the railway traincommences its movement, and the axles of the vehicle turn through aportion of their rotation. The rod 0 is then moved in the direction ofthe arrow II, Fig. 11, whereby the friction-transmitting gear-wheel c isthrown into gear with the friction gear-wheel Z), and the valve 19 isopened to admit compressed air from the reservoir n to the cylinders q,whereby the pistons K are reciprocated and the counter-shaft e isrotated for imparting a rotary motion to the friction-gear wheel I), bywhich power is transmitted to the car-axle a for restarting, or aidingin restarting the car or other vehicle.

The apparatus may be arranged on one or more vehicles of a railwaytrain, or on vehicles of any description, and the movements of the rod 0are effected either by the guard from the interior of each vehicle, orbythe engineer on the locomotive.

The cylinders g, with their pistons and adjuncts, constitute an air pumpfor compressing and storing air in the reservoir 02, which air isutilized to restart the vehicle through the medium of the cylinders gand their pistons.
